Clatskanie, OR

Image 

JH Kelly is constructing this dry mill ethanol plant, the largest on the West Coast and one of  the ten largest in the US. The plant will have a capacity of  108 million gallons per year (gpy) of undenatured ethanol with a design basis of operating 24 hours per day for 350 days per year.

JH Kelly will self-perform the following activities:

  • Site preparation - 7,000 lf roadway with truck scales; 24,000 lf rail spur with rail scales and unit train grain unloading system sized for ten storage days; and stone columns for soil stabalization
  • Concrete - 17,000 cubic yards of concrete
  • Structural steel erection - 1,350 tons of structural steel and miscellaneous iron
  • Structures - 2,500 sf administration building, 2,400 sf maintenance building, 30,000 sf process building, DDGS loadout enclosure, DDGS dryer (complete drying system including a thermal oxidizer/ heat recovery steam generator), DD&E structure, fermentation equipment building and control room
  • Tanks, vessels and equipment - complete rail unloading and grain handling system, four carbon steel tanks, 20 stainless steel tanks, nine major process vessels including distillation beer column and ethanol dehydration molecular sieves
  • Piping installation - 82,000 lf of pipe, over 175 miscellaneous pumps, heat exchanger, compressors, and blowers
Special points of interest:
  • 82,000 lf of pipe fabricated and installed by JHK
  • Peak manpower of 250
  • Largest ethanol plant on the West Coast and one of the ten largest in the US
  • 21 month duration scheduled to complete in Spring 2008
